ABSTRACT
The integration of heterogeneous information sources is an important data engineering research issue. Various types of information sources are available today. They include dissemination-based information sources, which actively and autonomously deliver information from servers to users. We are developing a mediator/wrapper-based information integration system in which we employ ECA rules to define new information delivery channels, integrating multiple existing dissemination-based information sources. ECA rules in this system are derived from integration requirement specifications based on relational algebra provided by users. Dissemination-based information sources usually have data arrival properties, such as an information delivery schedule. Using the data arrival properties of underlying information sources, the system can derive more appropriate ECA rules and check the consistency of requirements more accurately. This paper proposes an extended scheme to process information integration requirements using source data arrival properties of dissemination-based information sources.
